"IHG corporate codes vary by brand. Airport Holiday Inns rarely check credentials, while InterContinentals in major cities almost always do. The likelihood of a request for ID is based on the size of the discount — the greater the discount, the more diligent the front desk. Be prepared to be asked for company ID if the discount rate is more than the standard 15% given to most corporates, or if the company rate is a fixed rate lower than the hotel's ADR. Cisco's IHG code (954410926) sits alongside IBM and Dell in the widely-circulated FlyerTalk master list; tech-company codes at this tier typically yield 10-25% savings and trigger occasional verification at full-service properties but rarely at Holiday Inn Express tier."

"The Walmart IHG code is widely discussed online. Analysis confirms: "IHG might occasionally ask for verification, such as a Walmart employee ID, upon check-in. IHG may cross-reference submitted information with Walmart's employee database." Enforcement is tier-based: airport Holiday Inn Express properties rarely check while InterContinentals almost always do. With 1.6M+ US Walmart employees, hotel staff are familiar with what Walmart IDs look like, making false affiliation claims harder to sustain."

"FedEx Freight American Freightways (954105683) is an IHG code for a FedEx freight division. The FedEx/IHG enforcement pattern applies across all FedEx business unit codes: IHG InterContinental properties request employee ID; IHG Holiday Inn Express properties essentially never do. FedEx's reported monitoring of hotel booking volume means anomalous usage could trigger company-side audit. FedEx employee IDs are standardized physical badges. Properties near FedEx facilities (Memphis TN, Indianapolis IN) are most verification-active."
